The investigation was conducted during three successive seasonsof2016/2017, 2018/2019 and 2019/202020 to study the effect ofselection in Giza 3 variety for increasing seed yield of broad bean. The selected genotypes were evaluated in an experimental farm at the Faculty of Agriculture at Al-Azhar University, Assiut Branch. The results showed that the average values ​​in cycle 2 were higher than the averages in cycle 1 for all studied traits, except for the number of days to maturity, its average values ​​in the cycle 1 were higher than the average values in the cycle 2. Also, the selected plants recorded higher values​​than the average values ​​of the base population and the check cultivar. The actual response to selection was higher than the expected response to selection in all studied traits. The phenotypic and genotypic coefficients of variability recorded lower values ​​in cycle 2 and higher values ​​in cycle 1 of all the studied traits. The phenotypic and genotypic correlation coefficients were positive and significant between seed yield per plant , plant height , number of pods per plant and weight of 100 seeds , except for days to maturity were negative and significant. High heritability values ​​were recorded in the narrow sense (<50%) for seed yield /plant in cycle 1 and cycle 2, and ranged from low to medium for the remaining traits.
